The Minya Coptic Orthodox Diocese said that celebrations will be limited to liturgical prayers 'without any festive manifestations'

Egyptian churches, in the southern city of Minya, said on Tuesday that they will not hold Easter celebrations in mourning for 45 Coptic Christians killed this week in twin bombings of churches in two cities during Palm Sunday ceremonies.

The Minya Coptic Orthodox Diocese said that celebrations will only be limited to the liturgical prayers “without any festive manifestations.”

Minya province has the highest Coptic Christian population in the country. Copts traditionally hold Easter church prayers on Saturday evening and then spend Easter Sunday enjoying large meals and family visits.

Parliament approved on Tuesday President Abdel Fattah el-Sissi’s decision to declare a three-month state of emergency following the attacks, an action seen as a foregone conclusion since the legislature is packed with el-Sissi supporters. The Cabinet declared it had gone into effect as of 1pm on Monday.

The unicameral chamber preliminarily approved amendments to a set of laws on Monday aimed at speeding up the trials of those charged in terrorism-related cases.

Following the attacks, el-Sissi ordered the formation of a new body called the Supreme Council to Combat Terrorism and Fanaticism.

Sunday’s bombings, claimed by ISIS, are the latest escalation by the extremist group — which recently vowed to step up its attacks against Egypt’s embattled Christian minority.

The group had claimed responsibility for the December bombing of a church adjacent to St Mark’s Cathedral in Cairo, one of the most symbolic religious sites for Egyptian Copts. That explosion killed 30 worshippers and injured dozens.
